hey all anyone have any words of wisdom on installing car stereo speakers? last fall, i replaced the stereo in my van (easy enough), but it was a much stronger stereo than the 20+ year old stock system. its rated at 100 watts (25 watts per channel). the stock speakers couldn't handle it. they farted out really bad. so, i replaced the 2 back speakers with ones rated well above the 25 watts. they are, however, only 6" speakers (space constraints). so, they still fart out on the mids and have almost no bass. is there something i am missing as far as speakers go? i did not expect great bass response from 6" speakers, but, i did expect them to handle the power of the stereo. praytell, what am i doing wrong?!?!?!?!?
